Démarrage impossible (écran noir)
Bonjour à tous,
depuis quelques temps, le démarrage sur Ubuntu 20.04 ne marche plus. Après l'écran du Grub, je reste sur un écran noir.
J'arrive toutefois à démarrer si je choisis les options avancés et une autre option (de mémoire 5.8.0-53-Generic)
J'ai lancé une session live et un boot-repair mais rien n'a changé.
Pour info, voici le 'diagnostic' de bootInfo:

Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would purge (in order to sign-grub) and reinstall the grub-efi-amd64-signed of
sda6,
using the following options: sda2/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix use-standard-efi-file restore-efi-backups
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your UEFI firmware boot on the L'OS actuellement utilisé - Ubuntu 20.04.3 LTS CurrentSession entry (sda2/efi/****/shim****.efi (**** will be updated in the final message) file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.
If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\****\shim****.efi (**** will be updated in the final message)
Quelqu'un pourrait-il m'aider?
Merci d'avance.

Re : Démarrage impossible (écran noir)
Bonjour.
Je note que tu peux démarrer avec un ancien noyau
Dans un premier temps, fais les dernières mises à jour en cas de correction du problème.
sudo apt update
sudo apt upgrade

"gedit admin:///etc/fstab" est proscrit, utilisez "pkexec env DISPLAY=$DISPLAY XAUTHORITY=$XAUTHORITY xdg-open /etc/fstab" Voir https://doc.ubuntu-fr.org/gedit

Il faudrait que tu regardes si tu ne pas installer un pilote graphique propriétaire. https://doc.ubuntu-fr.org/gestionnaire_ … prietaires

Re : Démarrage impossible (écran noir)
Si, lorsque tu bootes en mode recovery puis resume, la présentation graphique te convient, on peut généraliser.
Il faut modifier, avec un éditeur de texte, le fichier /etc/default/grub pour ajouter l'option nomodeset après les options quiet splash . La ligne devient alors
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
puis faire prendre en charge avec la commande
sudo update-grub
Sinon, il faudra mettre d'autres options à trouver.

Re : Démarrage impossible (écran noir)
J'ai fait comme tu m'as dit, mais la résolution est vraiment mauvaise (1400 x 1050) sans possibilité de la changer.
Mais ça l'a donné une idee; j'ai un peu triché du coup. J'ai utilisé Grub Customizer pour "faire remonter" la version qui fonctionne bien.
Je sais, les puristes vont me détester, mais je peux pas faire mieux pour l'instant.
Merci à toi en tout cas.

Re : Démarrage impossible (écran noir)
Quelle idée d'utiliser grub-custumer alors que c'est paramétable facilement par le grub
voir paragraphe 2.3 de https://doc.ubuntu-fr.org/tutoriel/grub … age_manuel
C'est la première ligne du fichier de parametre
probablement GRUB_DEFAULT=1>2
Pour changer de résolution, c'est le paramètre vga=xxx Voir paragraphe 3.3 du même document
Si tu as une idée de la résolution qui est bonne, il existe une table de correspondance.
Mais je pense que le pilote graphique nouveau finira par être réparé.

Re : Démarrage impossible (écran noir)
Oui, je sais... Mais je suis du genre flemmard et j'ai donc une préférence pour une interface graphique.
Je sais, j'ai un peu honte.
Mais j'essaierai avec les paramètres que tu me dis; juste par souci de perfectionnisme.
Merci en tout cas.
